Can't, for examples
"hdfs://x.x.x.x:9000/user/hive/warehouse/nzhang_part/ds=2010-08-15/hr=file," is
will be splited into
"hdfs://x.x.x.x:9000/user/hive/warehouse/nzhang_part/ds=2010-08-15/hr=file" and
"" by FileInputFormat.getPathStrings, "" will be checked by Path.checkPathArg
and
```
if( path.length() == 0 ) {
throw new IllegalArgumentException(
"Can not create a Path from an empty string");
}
```
you can see
```
FileInputFormat.setInputPaths -> FileInputFormat.getPathStrings ->
Path.checkPathArg
```
in hadoop for detail.
